UBB.Developers Forums Community Development Programming MySQL and Server Configuration Query to remove user from a particular group

Well... normally I would be empathetic... but you've had yourself 2 vacations in the last month. LOL

And here's what came of my attempt to remove said user from that group:

Error

SQL-query :

UPDATE w3t_Users SETU_Group = '-3-7-' WHERE U_Username = 'Jamie Friebel'

MySQL said:

Unknown column 'U_Group' in 'field list'

I tried it through the admin interface and through phpmyadmin... same deal. Any ideas?
